Some classes may be deleted from the repo, others renamed

I found these classes:

• FeatureForceTorque
• FeatureForceTorquePreint
• FactorForceTorque
• FactorForceTorquePreint

where the ones without the 'preint' seems they are not used.

I propose deleting these classes, and renaming the 'preint' ones without the 'preint':

• FeatureForceTorquePreint --> FeatureForceTorque
• FactorForceTorquePreint --> FactorForceTorque

Also, I propose to eliminate all references to preint in other classes, because it is not very informative and the names are already very long:

• CaptureForceTorquePreint --> CaptureForceTorque
• ProcessorForceTorquePreint --> ProcessorForceTorque
• ProcessorForceTorqueInertialPreint --> ProcessorForceTorqueInertial
• ProcessorForceTorqueInertialPreintDynamics --> ProcessorForceTorqueInertialDynamics

Finally, I propose to eliminate a dangling processor that nobody uses, and rename another one with its name (@asanjuan this concerns your work):

• Delete ProcessorForceTorqueInertial
• ProcessorForceTorqueInertialDynamics --> ProcessorForceTorqueInertial
